FIELD: medicine.
SUBSTANCE: invention refers to medicine, namely to cardiovascular surgery, and can be used for small-diameter vessel prosthetics. Biological vascular prosthesis with a reinforcing external frame consists of a biological part represented by decellularised vascular material of cattle, preserved stabilizing agents, and a reinforcing outer carcass made of polymer materials. Reinforcing outer frame is made using an extrusion method and has a spiral with a pitch value of 0.1–10 mm and a filament thickness of 0.1–1 mm, in the edge part terminating with a circular element.
EFFECT: technical result of a biological vascular prosthesis is the creation of a reinforcing outer frame with a regular structure, maximally repeating the relief of the vessel, which does not require additional fixation by connecting sutures and delivers additional bending rigidity to the biological base.
